Hi Mike no it s not a wiring diagram problem its electrical on the tractor some where i,ve tryed changing relay switches but to no avail what happened was we had temporary lights on the trailer and the cable was left along the floor of the trailer the cable got damaged fused all the wires together the lights were plugged in when the lights were switched on it blew out the work lamps on the tractor checked all the fuses still no lights

I understand what you are saying but Im afraid there is no specific area I or anyone could point to for you no, not in this sort of a case.. The initial places to point to in the case of a burn out of the wires would only be to where you can see and follow the wires through.

I have seen a whole car wiring loom with 70 wires in it burn in an "instant" when one person connected up the battery incorrectly - it just burns so fast you simply cannot trace it / put a finger on it - you just have to go through the wiring fully ...as you say in your case, the wires burned - a similar thing has happened. For this to have happened in your case, the cause must have been a shorting to either an earth / metal point somewhere in the wiring on the vehicle - or, between a live and earth wire - so you could check the starting points - but you would have to physically and visually check the wiring through Ivan so that once you have repaired the obvious, on reconnection, the same doesn't happen again. Once you are sure all is put right, you can use a volt meter on "amps" mode to check for continuity of all the wires - and the earth circuits - but ensure you test the live circuits first...

I hope you understand what Im meaning above but do let me know if you need anything else - anything that I can help with more so , Im more than happy too..

I have just re read through what you have said to be sufre I haven't missed anything - and I note you say the cable was left lying - an it got damaged..so thats your point at where the incident was "caused" - so its not like you have to go looking for the cause... its now a case of checking it through as above Ivan and replacing the damaged / burned wiring as found -

Let me know if you need anything else on this -
